Resumen

A putative dehalogenase, l-HAD_ST, from the thermophile Sulfolobus tokodaii, was cloned and expressed in Escherichia coli. The recombinant enzyme catalyzes the stereospecific dehalogenation of l-2-haloacids with similar levels of activity as its homolog from mesophiles. l-HAD _ST remains fully active after being incubated for 4 h at 70 °C and tolerates extreme pH conditions ranging from 4 to 10. Furthermore, it can be purified conveniently without the usage of any chromatography method. The high expression yield and easy purification procedure make the recombinant dehalogenase an excellent candidate for biotechnological applications.
